Abstract: A resin is provided which is the adduct of a bisphenol and a diglycidyl ether of a bisphenol reacted with an anhydride to an Acid No. of 35 to 150. This resin is solubilized with a volatile amine, ammonia, or NH.sub.4 OH in a solvent mixture of water, alkoxyethanols, alcohols, and alkyl ethers of diethylene glycol and combined with an aminoplast to produce a coating composition utilizable to coat metal surfaces that will contact a food or beverage, such as in metal packaging containers.

Abstract: A process for preparing thermoplastic polyether resins from bisphenols, particularly having significant quantities of the o, p- or o, o-isomers such as bisphenol A and epoxy resins such as the diglycidyl ether of bisphenol A is improved by the addition of small quantities of a halogenated bisphenol such as tetrabromobisphenol A preferably near the end of the reaction. The process provides a product higher in molecular weight than that obtained without the use of the halogenated bisphenol.

Abstract: A method of cationic electrodeposition on an electroconductive substrate is disclosed. The method of the invention employs as the electrocoating vehicle an aqueous dispersion of a quaternary ammonium carbonate-containing resin. Electrodeposition of the resin is accomplished without generating harmful acid from the counter ion. The carbonate counter ion is continuously evolved from the electrodeposition bath at the anode as carbon dioxide.The quaternary ammonium carbonate-containing polymers are also useful as feed resins for controlling the pH of aqueous dispersions of acidified cationic resins used in electrodeposition. Upon electrodeposition, these resins generate acid which can build up to undesirable levels in the electrodeposition bath. The quaternary ammonium carbonate-containing polymers are relatively basic and when fed into the bath react with the acid to form the corresponding quaternary ammonium salt of the acid releasing carbon dioxide.

Abstract: The use of cyclic carbonic acid esters of the formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which may be the same or different, are hydrogen or alkyl with 1 to 6 C-atoms, as a solvent for racemic or optically active poly-(.beta.-hydroxybutyric acid).The preferred embodiment uses hot (120.degree. to 150.degree. C) ethylene carbonate or 1,2-propylene carbonate to extract poly-(.beta.-hydroxybutyric acid) from moist or dry fermentation masses. These solvents have the advantage that the extracted poly-(.beta.-hydroxybutyric acid) is precipitated in good yield from them on cooling. In addition they may be recycled without the need for a solvent regeneration step. These cyclic carbonic acid esters may also be used as the solvent in the processing of poly-(.beta.-hydroxybutyric acid) by e.g. wet spinning.
